Run before,afterAlls as 'eachs' when specifying runnablesToRun

- Fix bug where beforeAlls were being mutated in Suite#execute
- When Env.execute() receives a list of runnables, beforeAlls and
  afterAlls are collected as beforeEachs and afterEachs. This allows
  runnables to be specified in any order, regardless of if any of them
  have before/afterAlls.
- Spec constructor takes a single function that returns both before and
  afters, instead of two functions. This breaks the current interface
  for constructing a Spec.
